Nice review Phil. I especially enjoyed the embedded nail experiment! I do beleive it is pronounced "Froyd." Also what you were calling "gulleys" are technically called "gullets" and they are really important for material removal to help keep the blade moving forward, faster and reducing burning. Combo blade (higher TPI) gullets are usually shallower than rip blade (lower TPI) gullets because the combo blade is designed as much for cutting wood fibers which usually produces much smaller chips (also taking it longer to make rip cuts). Rip blade gullets tend to be deep because the blades are designed to "chip" away at the wood producing larger chipsmaking and making faster cuts than combo or crosscut blades. Last thought on blade thickness (kerf). I prefer to use thicker kerfed blades on my table and job site saws - they are more stable with less wobble than the thin kerf variety, especially on deeper cuts. Thicker kerf blades also seem to remove material more efficiently than thin kerf blades allowing the blades to run smoother and cooler. Keep em coming...

Are you sure its not pronounced Fr-oy-d? Like sigmund freud? 😂
